In this paper we propose a novel approach for the bit allocation performed in an ADSL modulator. This new method is based on the observation that the transmission speed using ADSL strongly depends on the distance between the central office and the subscriber's side and does not permit real-time transmission for high bitrate video on long distances. The algorithm we develop takes into account the characteristics of a video sequence and distributes the channel error according to visual sensitivity. This method involves variable transmission Bit Error Rate.
